Thought I'd share a bit of excitement, a functioning anti-lag program! I still need to work out some bugs but it's made my car much more entertaining! It should really be called launch assist because it's not active above 3mph but who cares.

Alright, inbetween replacing my crank I uploaded a mildly tuned $32B file on post #3 for everyone looking for a replacement for the 'F' or 'L' bins. I will upload definitions once I track down copies. If anyone finds a problem with it shoot me a PM and I'll see what I can do.

Ill have that bin file chip to you tomorrow in the mail. Heres the link for the aldl cable its a 12 pin usb cable. I don't wana mess with BL85c's bin till I know what your cars going to want with it. So datalogging is a must.

The ECM swap worked thanks bl85c, although I had to move B6 back to B6 instead of B12. The New wire part of the chart should be updated and more specific. In my opinion, you should say something like: cut one of the disconnected wires, and place this cut wire with the terminal in D10 and splice it with A12 while leaving A12 connected to it's original wire and its terminal location on the connector. Just makes it alot clearer, I think.

The car so far seems a bit sluggish when accelerating (although, I didn't do any relearn procedures or really drive it...I will tomorrow), and it has a hesitation when taking off from a stop. What causes this in the bin? and why did I have to move B6 back?

I used the bin you provided. It dips in the RPMs when you tap the gas and then it will go up soon after. Only from a stop or while in park. It is a bit sluggish compared to the 302, while accelerating as well. Also when above 35ish and going between 35-40 it knocks guess the deceleration or TCC? I think in the bin you provided it is set to 37 MPH. I just want to establish what is and isn't normal.

For example, my tach says 1200 RPM in park warm (I know inaccurate) and then when I hit the gas it will goto 800-1000 for a second then go up in RPMs like it should.

I think your problem is maf related. Not sure why you need it on B6, B6 is what the '302 ecm uses, the '165 uses B12 for MAF.

Could it be because the flag "Analog MAF In Use" isn't checked or "Set," in the bin?

I tried B12 and got code 34.

I have a new AC Delco 213-167 MAF sensor hooked up to my car with no codes on B6 and on my 302 ECM and with code 34 (low freq) on B12 on the 165 ECM.

According to the GM manual, the V6 MAF should get 2.5 volts running and key on, and the V8 MAF should be 2.5 volts key on and .4-1 volts engine running. Hmm, which is why the MAF is getting a low reading on B12 I think? Both the 302' and 165' B6 is 2.5 key on and 2.5 engine running, which would explain why my MAF works fine on B6.

So why does it work on your set-up? You must have a different type of MAF or something...I don't know. It still doesn't explain the dip in RPMs or hessitation when the gas pedal is first pressed.

I tested it some more, if I very lightly touch the gas and hold it...very very lightly...it will burble the idle...if I press it just a tad more it will act normal and raise like it should. Hmm...I don't think it's MAF related. This only happens just off idle and causes my car to slightly hesitate from a stop, then it will act normal as I accelerate.

It seems to be hard to get past 55 sometimes as well while other times it cruises to 70...uhhh this thing is poop. I think the TCC and Dec settings need to be tweaked? I am not sure.

If you are using the stock v6 MAF then it's digital and that flag shouldn't be checked. The '165 ECM reads MAF info from B12, the MAF needs to be on B12. Even if you can see a g/sec value in your data logs it doesn't necessarily mean it's reading the MAF, when there's a MAF problem it will revert back to another table and that's what you see in the g/sec field. Not sure why you don't have an error flag for the MAF but everything's pointing to MAF problem. Back probe your MAF connector and see what's going on, then put it on B12 and do the same if it will run. I will look through the bin file I posted some more but this is basically the same file that's been on Moates' website for years with minor changes... fasteddi or whoever is doing the burning, out of curiosity can you tell me what happens if you disable err 34 in the bin and try to run it?

I just ran my 302' ECM and it runs like a dream...with my stock v6 MAF. I drove the 165' ECM 70 miles one trip, it was shuttering when accelerating, it had power loss up hills, the TCC felt weird, and just sucked...even used more fuel. I had to repin and swap ECMs to get home..lol I don't know. I had it repinned correctly except for B6 --> B12. It just doesn't work on B12. It throws Code 34.

Also the 165' doesn't support the v6 A/C system? The clutch control wire is disconnected where do I connect it?

I bought a burner online and the cable nec. to datalog, I am hoping to get it this week...then I can hopefully do this with any edits to the bin.

I don't know why the MAF would not work on the 165 but on the 302 just fine. Could the memcal have to do with it? I am using the G1 adapter from moates.

I'll try it again soon, I think I checked that bin and I didn't see code 34 error anywhere in the flags, tables, or scalars....hmm

No A/C control with the '165 ecm unfortunately, just tape the connector up. Here's a hack of $32B, you can add the err 34 flag if it's not in your definition file. When you get your cable post a datalog. I don't see the adapter being a problem and I'm certain the digital MAF works w/ the '165, I had it on my car a year with $32B but something's not jiving here. If anyone has an original "F or L" bin post it up for comparison please.

That's what I was just looking at actually, I went back through old threads looking for info on the MAF pin. Chris you're right it belongs on B6 with the digital MAF , so that leaves calibration as the problem. Will go through the bin again and update the repin guide.

Eddi...I think I found the problem, I will confirm it later. You used the wrong 32B XDF file so the MAF tables are wrong, and other stuff. I have the V6 XDF file needed for the bin bl85c provided. :P I bought a burner, didn't think I was going to go all out...lol Only question I have is do I try it on B12 or stay on B6?

I'll try it later and report back. Thanks for the help everyone...I will see what happens and give an update.

Also bl85c, do I need to add a Scalar for the flag? Which hex address should I use? output type? and significant digits? what should the gm/sec be for "too low"

Don't worry about adding the err 34 flag unless you want to, it's not needed now. Leave it on B6 that's the pin for digital input. I still haven't found anything in the calibration that should cause this unless the MAF tables are plain wrong for your induction setup and need tweaking... does your MAF still have the screen?

Maybe it's not going into closed loop because of a bad temp sensor or something... I'm just waiting on a datalog at this point. When you record it make sure you record from first start (cold) till normal temp.

bl85c, I think it isn't working right because the bin was burned with the wrong XDF File. I must of sent fasteddi the wrong file. I am going to burn the bin with the V6 32B XDF.

I think that will clear things up.

Next thing I would like to try to figure out after this is:If there is a way to run my A/C system, I think I could make the compressor clutch run all the time when the A/C is on maybe?

The car still hesitates from a stop and jerks while driving randomly with the fresh bin burn I just did.

uhhhh, is there anyway to modify the bin so it is near stock to the 302? So I can at least have my car as a daily driver without swapping pins back and fourth because I have the G1 ZIF...until I can datalog it...which btw what program should I use?

D3 on 165 ECM is suppose to be grounded but the repin guide doesn't mention it.
Also B7 is the ESC Signal is that not used from the 2.8?
